You will NEVER SEE one of these again, I'd bet, outside of a book on historic minerals of Cornwall (and even then, I don't think there was a photo in THE History of Cornwall Minerals book, was there?!). I had never seen one, outside of browsing a copy of Sowerby's Exotic Mineralogy! They were found rarely in the late 1700s or early 1800s; and nobody I have spoken to knows of another piece of any significance to hit the market in decades. Moreover, aside from the significance of its mere existence and availability for sale, it is as dramatic as a grey-colored mineral can be, with sparkly crystals rising dramatically to 3 cm in height! I have privately shown the specimen to several European experts who have confirmed that it is as rare and desirable as I say, and that it is indeed English and not French or German. Note also that it was an early specimen in the collection of Carl Bosch, who was noted for his superb suites of old classics. The back of the old label seems to indicate whom he purchased it from.

If the acid is dilute hydrochloric acid, the chemical reaction is:\n\u003C\u002Fp>\u003Cp>2HCl(aq) + CaCO3(s) -->> CO2(g)↑ + H2O(l) + CaCl2(aq)\n\u003C\u002Fp>\u003Cp>The most important & voluminous calcitic rocks in the world are limestone (sedimentary), marble (metamorphic), carbonatite (igneous), and travertine (speleothem, or \"cave formations\", and many hotspring deposits).  Quite a few hydrothermal veins in the world are calcitic or have calcite as a principal component.\n\u003C\u002Fp>\u003Cp>The dark yellowish coloration present in the calcite seen here is from significant iron impurity.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Galena is a lead sulfide mineral (PbS).  It has a metallic luster, silvery-gray color, cubic crystals, cubic cleavage, is moderately soft, and has a very high specific gravity (it's very heavy for its size).\n\u003C\u002Fp>\u003Cp>Galena is the most important lead ore mineral.  It's principally found in hydrothermal vein systems and in Mississippi Valley-type deposits.  Silver (Ag) can fall into the lead position as an impurity, sometimes in relatively high proportions.  This results in argentiferous galena, (Pb,Ag)S.\n\u003C\u002Fp>\u003Cp>Historically, lead from galena has been used as a gasoline additive, a paint ingredient, and for making bullets.  Lead is also used to make various metal products, batteries, and radiation shielding.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>This specimen comes from a polymetallic sulfide ore body at the famous Dalnegorsk skarn deposit in far-eastern Russia.

At its simplest, a mineral is a naturally-occurring solid chemical.  Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common.  Mineral classification is based on anion chemistry.  Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.\n\u003C\u002Fp>\u003Cp>The sulfide minerals contain one or more sulfide anions (S-2).  The sulfides are usually considered together with the arsenide minerals, the sulfarsenide minerals, and the telluride minerals.  Many sulfides are economically significant, as they occur commonly in ores.  The metals that combine with S-2 are mainly Fe, Cu, Ni, Ag, etc.  Most sulfides have a metallic luster, are moderately soft, and are noticeably heavy for their size.  These minerals will not form in the presence of free oxygen.  Under an oxygen-rich atmosphere, sulfide minerals tend to chemically weather to various oxide and hydroxide minerals.\n\u003C\u002Fp>\u003Cp>Pyrrhotite is imperfect iron monosulfide (Fe(1-x)S).  The atomic structure of pyrrhotite has holes due to an insufficient number of iron atoms, cf. sulfur atoms.  Iron monosulfide is a common, but minor, component of many meteorites, but it lacks the atomic-scale “holes” of pyrrhotite, and is called troilite (FeS).\n\u003C\u002Fp>\u003Cp>Pyrrhotite is superficially like pyrite in appearance and chemistry, but they are different minerals.  Pyrrhotite has a metallic luster, a brownish-brassy or bronzish color, a black streak, no cleavage, and is magnetic.  What’s particularly distinctive about pyrrhotite is that it is variably magnetic.  The holes in the atomic structure gives pyrrhotite its magnetism.  But, there's variation in the number of missing iron atoms from sample to sample, so pyrrhotite ends up having variable magnetism.  More holes results in stronger magnetism.  Few holes results in weaker magnetism.\n\u003C\u002Fp>\n\u003Chr>\n\u003Cp>Photo gallery of pyrrhotite:\n\u003C\u002Fp>\n\u003Ca rel=\"nofollow\" class=\"external text\" href=\"http:\u002F\u002Fwww.mindat.org\u002Fgallery.php?min=3328\">www.mindat.org\u002Fgallery.php?min=3328\u003C\u002Fa>",2708,[1511,1517,1522],{"id":1512,"url":1513,"label":1514,"formula":1515,"spacegroup":1516,"year":666},5392,"\u002Fcif\u002F5392.cif","Noda 1987","Pb S","F m 3 m",{"id":1518,"url":1519,"label":1520,"formula":1515,"spacegroup":1516,"year":1521},5397,"\u002Fcif\u002F5397.cif","Wyckoff 1963",1963,{"id":1523,"url":1524,"label":1525,"formula":1515,"spacegroup":1516,"year":1526},5398,"\u002Fcif\u002F5398.cif","Ramsdell 1925",1925,[1528,1529,1530,1531,1532,1533,1534,1535,1536,1537,1538,1539,1540,1541,1542,1543,1544,1545,1546],"Acerilla","Allquifoux","Bleiglanz","Bleyschweif","Blue Lead Ore","Carne de vaca","Galenita","Galenite","Glasurerz","Lead Glance","Lead sulphide","Lead sulphuret","Lead-ore","Parakobellit","Parakobellita","Parakobellite","Potter's Ore","Steinmannit","Sulphuret of Lead",[1548,1552,1557,1561,1564,1568,1572,1576,1580,1584,1588,1591,1595,1599,1602,1606,1610,1614,1619,1622,1626,1631,1642,1645,1650,1654,1658,1661,1664,1667,1671,1675,1680,1683,1687,1691,1694,1698,1703,1706,1710,1714,1719,1723,1726,1729,1733,1736,1739,1743,1747,1750,1753,1756,1759,1762,1765,1768,1772,1775,1778,1781,1786,1790,1794],{"lang":1549,"names":1550},"af",[1551],"Galeniet",{"lang":1553,"names":1554},"ar",[1555,1556],"جالينا","غالينا",{"lang":1558,"names":1559},"arn",[1560],"Galeneishon",{"lang":1562,"names":1563},"arz",[1555],{"lang":1565,"names":1566},"az",[1567],"Qalenit",{"lang":1569,"names":1570},"azb",[1571],"قالینا، آلاسکا",{"lang":1573,"names":1574},"be",[1575],"Галеніт",{"lang":1577,"names":1578},"bg",[1579],"Галенит",{"lang":1581,"names":1582},"bs",[1583],"Galenit",{"lang":1585,"names":1586},"ca",[1587,15],"galena",{"lang":1589,"names":1590},"cs",[1583],{"lang":1592,"names":1593},"cv",[1594],"Хура тăхланла ялтрав",{"lang":1596,"names":1597},"da",[1598],"Blyglans",{"lang":1600,"names":1601},"de",[1530,1583,1541,1545],{"lang":1603,"names":1604},"el",[1605],"Γαληνίτης",{"lang":1607,"names":1608},"eo",[1609],"Galeno",{"lang":1611,"names":1612},"es",[1587,1613],"michoso",{"lang":1615,"names":1616},"et",[1617,1618],"galeniit","pliiläik",{"lang":1620,"names":1621},"eu",[7],{"lang":1623,"names":1624},"fa",[1625],"گالن",{"lang":1627,"names":1628},"fi",[1629,1630],"galeniitti","lyijyhohde",{"lang":1632,"names":1633},"fr",[1634,1635,1636,1637,1638,1639,1640,1641],"galène","galenite","johnstonite","parakobellite","plomb argentifère","plomb sulfuré","sexangulite","sinkanite",{"lang":1643,"names":1644},"gl",[7],{"lang":1646,"names":1647},"he",[1648,1649],"גלנה","גלניט",{"lang":1651,"names":1652},"hr",[1583,1653],"Olovni sjajnik",{"lang":1655,"names":1656},"hu",[1657],"galenit",{"lang":1659,"names":1660},"ia",[7],{"lang":1662,"names":1663},"id",[7],{"lang":1665,"names":1666},"io",[1609],{"lang":1668,"names":1669},"is",[1670],"Blýglans",{"lang":1672,"names":1673},"it",[1587,1674],"piombo argentifero",{"lang":1676,"names":1677},"ja",[1678,1679],"ガレナ","方鉛鉱",{"lang":1681,"names":1682},"kk",[1579],{"lang":1684,"names":1685},"kn",[1686],"ಗಲೀನ",{"lang":1688,"names":1689},"ko",[1690],"방연석",{"lang":1692,"names":1693},"ky",[1579],{"lang":1695,"names":1696},"lt",[1697],"Galenitas",{"lang":1699,"names":1700},"mk",[1701,1702],"галенит","оловен сјајник",{"lang":1704,"names":1705},"mn",[1579],{"lang":1707,"names":1708},"nb",[1709],"blyglans",{"lang":1711,"names":1712},"nds",[1713,1583,1545],"Bliegleem",{"lang":1715,"names":1716},"nl",[1717,1718],"galeniet","Loodsulfide",{"lang":1720,"names":1721},"nn",[1722],"galenitt",{"lang":1724,"names":1725},"no",[1598],{"lang":1727,"names":1728},"oc",[7],{"lang":1730,"names":1731},"pl",[1732,1587,1657],"błyszcz ołowiu",{"lang":1734,"names":1735},"pt",[1587],{"lang":1737,"names":1738},"pt-br",[7],{"lang":1740,"names":1741},"ro",[1742],"galenă",{"lang":1744,"names":1745},"ru",[1579,1746],"Свинцовый блеск",{"lang":1748,"names":1749},"sco",[1587],{"lang":1751,"names":1752},"sh",[1583],{"lang":1754,"names":1755},"sk",[1657],{"lang":1757,"names":1758},"sl",[1657],{"lang":1760,"names":1761},"sr",[1701],{"lang":1763,"names":1764},"sv",[1598,1583],{"lang":1766,"names":1767},"tg",[1579],{"lang":1769,"names":1770},"th",[1771],"กาลีนา",{"lang":1773,"names":1774},"tly",[1587],{"lang":1776,"names":1777},"tr",[1583],{"lang":1779,"names":1780},"uk",[1575],{"lang":1782,"names":1783},"uz",[1583,1784,1785],"Qo‘rg‘oshin yaltirog‘i","Qoʻrgʻoshin yaltirogʻi",{"lang":1787,"names":1788},"vi",[1789,7],"Galen",{"lang":1791,"names":1792},"wuu",[1793],"方铅矿",{"lang":1795,"names":1796},"zh",[1793],"Q37559",{"history":1799,"applications":1804},{"markdown":1800,"model_version":1801,"prompt_version":1802,"reviewed_at":1803},"Long before any Greek or Roman naming, Egyptians ground galena into a black powder and lined the eyes with it. The kohl was thought to reduce the glare of the desert sun and to repel flies[1]. Across the Atlantic, pre-Columbian peoples of North America used galena in decorative paints and cosmetics for similar pigment effects[2]. Lead could be smelted from galena in an ordinary wood fire — a low-tech process available wherever the ore was found[3].\n\nPliny the Elder gave the mineral its written name in 77–79 CE, taking *galene* from the Greek — the word for *lead ore*[4].\n\nIn the early 20th century, the same mineral found a brief new career in radio. A polished crystal of galena, touched by a fine wire, acted as a point-contact diode. It rectified alternating current and pulled weak radio signals out of the air for the crystal radio receivers of the first wireless era[5].","claude-opus-4-7","1.7.0","2026-06-01 15:30:41",{"markdown":1805,"model_version":1801,"prompt_version":1802,"reviewed_at":1806},"Galena is the world's most important source of lead[1]. Many of its deposits yield silver as a co-product as well[2].\n\nThe bulk of that lead becomes lead-acid storage batteries. In the United States, batteries accounted for about 88 percent of lead consumption by the early 2000s[3]. Smaller fractions go into ammunition, glass and ceramics, casting metals, and sheet lead — none above a few percent of national demand[4]. Lead also serves as radiation shielding in medical analysis and video display equipment[5].\n\nWhere ore bodies carry enough silver in solid solution, the two metals are recovered together — the silver as a by-product of lead refining[6].\n\nSignificant producing regions include Australia, Idaho, Germany, Cornwall, and Mexico[7].","2026-06-01 15:31:40"]
